1. One kilogram of R-134a fills a 0.090 m3 rigid container at an initial temperature of -40°C. The container is then heated until the pressure is 280 kPa. Determine the initial pressure and final temperature.
2. A rigid tank with a volume of 0.117 m3 contains 1 kg of refrigerant-134a vapor at 240 kPa. The refrigerant is now allowed to cool. Determine the pressure when the refrigerant first starts condensing. Also, show the process on a P-v diagram with respect to saturation lines.
